Title: Improvements in or relating to tube conveyor systems
IPC: B65G51/42
Filed: 1933-03-28
Abstract: 402,983. Pneumatic dispatch apparatus. TELEPHON - APPARAT - FABRIK E. ZWIETUSCH & CO., GES., 6, Salzufer, Charlottenburg, Berlin. March 28, 1933, No. 9368. Convention date, Jan. 19. Addition to 390,996. [Class 116.] The parent Specification described a tube conveyer system having a reading unit located at a control station and arranged to engage rotatably adjustable members on the carrier for the purpose of controlling its destination and in which the reading unit is rotated when the position of the carrier within the tube is unsuitable for the reading operation. In the modification according to the present invention the control is effected by circumferentially arranged feeler pins which are actuated radially by the insertion of the carrier into the tube and co-operate with the carrier to initiate the reading operation or to rotate when necessary, the reading unit to a position suitable for the reading operation. On the insertion of the carrier into the tube, feeler pins S1-S8 are moved inwardly, and according to the angular position of the carrier a projection E is engaged by a projection M or a shoulder F of one of the feeler pins. With each feeler pin is associated a group of contacts 1, 2, 3 carried by a member T moving radially with the pin and capable of movement relative to the pin. When the projection E is engaged by the projection M of a feeler pin the movement of the frame T relative to the feeler pin S effects the closure of contacts 1, 3 and the opening of contact 2, with the energization of a relay R which permits the circuit operations for ascertaining the destination of the carrier as described in Specification 390,996. If the projection E is engaged by a shoulder F, or by the shoulders of two adjacent feeler pins, the movement of the member T relative to the feeler pin closes contact 1 and does not open contact 2. Relay H energizes and effects the rotation of the reading unit to a position in which the reading operation is initiated afresh and the relay R energized, as in the previous case.

Abstract: 1,140,318. Seismic signal processing. PAN AMERICAN PETROLEUM CORP. 28 Feb., 1967 [10 June, 1966], No. 9565/67. Heading H4D. Apparatus for digitally convolving a set of input data x 0 , x 1 , . . . x n  (e.g. the digitalized output of a geophone) with a filter function comprises store 11 for storing the input data in serial order, store 13 for storing filter coefficients, and an accumulative multiplier 15 whose output (the sums of the products of the input data elements times the filter coefficients) is fed back to replace the corresponding x values in store 11. The feedback feature provides recursive filtering, which is economical in computation time, and produces a set of output data y 0 , . . . y n  by a two-step process yielding intermediate data v 0 , . . . v n . This process is given by where ai and b j  are sets of filter coefficients. In the first step, switch 17 is in the position shown and the x and b values are read out serially from stores 11, 13 to produce the v values at the output of multiplier 15. These v values are written into store 11 to replace the corresponding x values. In the second step, switch 17 (which may be mechanical or electronic) is in its other position and the v values in store 11 and a values in store 18 are read out serially and convolved (without recursion) in multiplier 15 to produce the y values on output 20. In a first modification of the process, store 18 is dispensed with and the a values are written destructively into store 13 when the first step has been completed. In a second modification, store 18 is again dispensed with and both sets of filter coefficients a, b, are stored serially in store 13 so that each v value can be used in the second step as soon as it is generated by the first step, i.e. the two steps are interlaced and effectively take place simultaneously.
